Evergreen shrub similar to golden chinkapin; mountains of California.

常綠樹超碰人妻人人干，類似金色的栗樹国产精品一级乱色视频；分布在加州的高山中。

The quick-growing plantation of Breakingfruit Chinkapin has sizeable stock measure in South China, though utilization research on Breakingfruit Chinkapin stays preliminary stage. Especially the research on utilizing the wood to make man-made panel is rarely reported in paper. So it is very important actual value and extensive development prospect to utilize Breakingfruit Chinkapin wood to make MDF.

黎蒴栲作為華南地區(qū)鄉(xiāng)土速生樹種具有相當(dāng)規(guī)模的蓄積量日本wwwwwwwwwwww，但是利用研究還處于起步階段黄网址资源站在线观看，特別是利用此樹種制造人造板的研究尚未見報(bào)道，采用黎蒴栲木材制造MDF具有廣闊的發(fā)展前景和重要的現(xiàn)實(shí)意義日本xx视频。

The object list is bright:( 1 ) Breakingfruit Chinkapin fibre's pH is lower , and it haw big Buffer capacity;( 2 ) Breakingfruit Chinkapin fibre has good permeability, When making MDF our should suitably enlarge Resin content;( 3 ) Along with compound than reducing of (Breakingfruit Chinkapin fiber / other wood fiber ), internal bond strength modulus of rupture, modulus of elasticity has trend that at first down than upward.

結(jié)果表明：（1）黎蒴栲材熱磨纖維的pH值低91精品视频一区，緩沖容量大；（2）黎蒴栲材纖維的滲透性良好午夜三级视频免费看，制造MDF時(shí)應(yīng)適當(dāng)加大施膠量视色网站视色视频；（3）隨著復(fù)合比（黎蒴栲纖維/其他樹種纖維）的減少，MDF的內(nèi)結(jié)合強(qiáng)度91插进去、靜曲強(qiáng)度深夜免费看、靜曲彈性模量成先下降后上升的趨勢(shì)。

The paper takes Breakingfruit Chinkapin fibre and other wood fiber compound manufacturing MDF's Processing-parameter for research object. Use the diagonal intersection trial law designing the trial scheme. The focal point is studied the major Processing-parameter of Breakingfruit Chinkapin with other woods to manufacture MDF. And internal bond strength, modulus of rupture, modulus of elasticity, formaldehyde emission content, thickness expansion rate of water absorbing and density of MDF are analysed. From Variance, Range and other methods seek the better Processing-parameter.
